Samsung hasn't confirmed the Galaxy S5 mini yet, but come on, we all know it's only a matter of time until we see it. We've already seen the rumored smartphone pop up on Samsung's website, and now it's been mentioned by name in a software update for the Samsung-specific Nok Nok Labs (NNL) Fingerprint Passport app.

The update, which was spotted by Android Central on Friday, adds support for "screen rotation and S5 mini," as you can see in the picture we snapped above. NNL Fingerprint Passport isn't an official Samsung app, so there's no guarantee the company has inside information concerning the Galaxy S5 mini. Still, considering this happened within the Samsung's own app store it's definitely possible we'll see the rumored smartphone launch with a built-in fingerprint scanner like the flagship S5.

The Galaxy S5 mini is expected to pack a 4.5-inch 720p display, an 8-megapixel rear camera, a 2-megapixel front-facing camera, a 2100mAh battery, 1.5GB of RAM, a Snapdragon 400 processor and run Android 4.4 with Samsung's own software on top. Recent reports suggest the device could launch as soon as next month, so it may not be much longer before we get an official look at Samsung's next smartphone.
